IPC: F16L21/02
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To sufficiently ensure sealed properties by providing on the outer surface of a base body fixed to an inert hole, a lip part which is brought in pressure contact with the inner surface of a hub by pipe internal pressure, hollowing the base body, and filling liquid into the hollow part of the base body. SOLUTION: A seal ring A for a pipe coupling is formed in such a way that liquid, for example, water, is filled into the hollow part 2 of an annular base body, and a lip part 4 is projected on the outer surface of the base body. A seal ring part (a) whose thickness corresponds to an interval between the highest part of the seal ring A and the inner surface of a hub 72, is crushed by the inner surface of the hub 72 by being inserted to the hub 72 of an insert hole 71, and the lip part 4 is brought in pressure contact with the inner surface of the hub 72 by compression stress against this crush, and also liquid 3 in the hollow part 2 of the base body is compressed and pressurized.  Under this condition, an interval between the lip part 4 and the root surface of the base body can be retained, the lip part 4 is brought in pressure contact with the inner surface of the hub 72 also by fluid pressure in the pipe of the lip part 4 so that this pressure contact force becomes high contact pressure as pipe inner pressure becomes higher and higher, thus the so-called self-seal action can be executed.

Title: Silicon carbide powder excellent in dispersibility and sinterability and its production
Inventor: SAYANO AKIO
IPC: C04B35/56
Filed: 1990-10-15
Abstract: PURPOSE:To obtain the title powder excellent in the dispersibility in solution, good in sinterability, capable of giving sintered compact products of high mechanical strength by heating silicon carbide powder in air so as to regulate its free silica content within a specified range. CONSTITUTION:The objective silicon carbide powder can be obtained by heating in air silicon carbide powder with a mean particle diameter of <=1mu so as to regulate its free silica content to 1-2wt.%. For the silicon carbide powder stock, when its mean particle diameter is > 1mu, its dispersibility will be poor; therefore, uniform, high-density product forms cannot be obtained, and sintered compacts with high mechanical strength cannot also be obtained because of lowered sinterability. The free silica formed as oxidized film on the particle surface improves the wettability of the particles to a solution and the particles' dispersibility in the solution. For these purposes, the content of free silica is preferable at 1-2wt.%.

Title: Image reader
Inventor: TSUKAHARA HAJIME
IPC: H02P8/14
Filed: 1994-11-08
Abstract: PURPOSE: To reduce vibration and noise of a motor by switching the clock frequency to be applied to a driver simultaneously with switching of excitation mode when the drive frequency reaches a set frequency within an audible frequency range. CONSTITUTION: Upon provision of a scan instruction, a CPU 18 reads in an instruction for setting scanning conditions from a ROM 19 and delivers a full step set signal, as an initial excitation mode, to an excitation mode switching terminal in a driver 20. Full step acceleration is executed upon depression of a scan start key. When a transfer motor 15 is driven and a set frequency is reached, it is detected by a CPU 18 which then delivers a half step signal, in place of the full step signal, to the excitation mode switching terminal of the driver 20 thus executing half step acceleration. When half step deceleration is performed, the motor is decelerated in a full step mode if the frequency is lower than the set frequency and eventually stopped. This structure reduces vibration and noise of the motor.
